Architecture and Roles
TSI Structure and Roles
TSI's architecture is designed with security, efficiency, and institutional needs in mind. It comprises three key components:
Fireblocks Embedded Wallet: This provides the foundational security layer. Using Multi-Party Computation (MPC), it ensures that no single party holds the complete private key, preventing unilateral actions and significantly reducing the risk of asset compromise. Key functionalities include:
Checking transaction stage conditions based on pre-set policies, ensuring all transactions adhere to predefined rules.
Requiring multiple signatures (from both the user and Fireblocks) for transaction execution, preventing unauthorized access and internal fraud.
TSI System: This is the core platform that orchestrates all borrowing, lending, matching, and liquidation processes according to pre-set rules. It acts as the central hub for all interactions within the TSI ecosystem, ensuring transparency and efficiency.
Client Web Application: This is the user interface through which borrowers, lenders, and liquidators interact with the TSI system. It provides functionalities for:
Placing borrow and lend orders.
Initiating asset transfers, leveraging the security of the MPC wallets for these actions.
Viewing order status, transaction history, and other relevant information.
